Goldline Rabbitfish (Siganus lineatus)
The Golden Lined Rabbitfish is a beautiful and active algae eater ideal for larger aquariums. Known for being a ravenous herbivore, it spends most of its time swimming in open areas, grazing on nuisance algae.
It features a light blue body with metallic gold lines, dots, and dashes, and a prominent lemon yellow blotch at the base of the tail.
Behavior and Compatibility
Can be added to reef tanks with caution. While they may show interest in some soft corals and fleshy LPS, many customers report that captive-bred specimens are completely reef safe and do not consume corals.
Diet
Best kept well-fed with a mixed diet of algae wafers, blanched vegetables, and other plant-based foods to reduce their tendency to target coral.

I’ve had my rabbitfish for six months now and it’s been a great addition to my 120-gallon reef tank. It constantly grazes on algae and doesn’t touch any of my corals. I feed it algae wafers and zucchini daily, and it’s always active and healthy.

The fish looks stunning with its gold markings and bright yellow tail. It’s very active and helps keep the tank clean. I’ve noticed it only nibbles on algae and hasn’t touched any soft corals, even after a few weeks.

After reading reviews, I was cautious about adding it to my reef setup. The rabbitfish has been perfectly safe and has kept the algae under control without damaging any corals. Feeding it a varied plant-based diet has made a big difference.
